This is confusing me so much.  I'm a day late and I've been pregnancy testing every day for the last week.  Yesterday's has the faintest, barely there line.  Out of curiosity I did an ovulation test (I have loads of those and I guess I'm addicted to peeing on sticks).  The ovulation test is glaringly positive but now I've started to bleed lightly.  I've got an intense pain in my lower back that feels a lot like the back pain you get in labour.  I had a miscarriage last month.  Do you think it's happening again?  Last month I had a positive test followed by cramps and very heavy bleeding.
